Sometimes, I really like to put quick launch apps in the panel like VLC Player to play my music just by one click. Sometimes, I like to keep tomboy in the panel to be in hand. But I don't know how to do that !

Another point. In Windows 7, there is a small application called sticky notes I'm sure you guys know. The most important feature that it can be stuck to the desktop holding important things to remember. Does tomboy do such a thing, or there is another app ?!
